Because with VOIP you can make calls from anywhere you have access to a broadband connection, users can take their IP phones or ATA’s with them on trips and still have access to what is essentially their home phone.

Some people use a softphone to access their VOIP service. A softphone is a specially developed software application that loads the VOIP service onto your desktop computer or laptop. Some even have an interface on the screen that looks like a traditional phone. These softphone applications allow you to place VOIP calls from your laptop; anywhere in the world you have access to a broadband connection.

Most traditional phone companies charge you for extra features that are added to your account. With VOIP service providers these usually come as standard. Features such as:

1. Caller ID

2. Call Waiting

3. Call Transfer

4. Repeat Dialling

5. Return Call

6. Three-Way Dialling

Some VOIP service providers also offer advanced call filtering features. These additional features allow you to decide how calls to a specific number are handled by using caller ID information. They allow you to:

1. Forward the call to a particular number

2. Send the call directly to voicemail

3. Give the caller a busy signal

4. Play a "not-in-service" message

Many VOIP services also allow you to check your voicemail over the internet or attach messages to an e-mail that is sent to your computer or PDA. It’s best to check with VOIP phone system suppliers and service operators exactly what features they offer as package and service prices vary greatly.

There are many other cost saving benefits that arise from a streamlined VOIP phone system network. For the network administrators, a VOIP phone system means they only have one network to maintain instead of two. The portability of the phone system is also greatly simplified. This is because most VOIP phone systems can be configured using a web interface, which can be managed by the network administrator. The MAC (move, add, change) process is made much easier, and you will not have to call your system/service provider for every MAC you carry out. All this means lower ongoing costs for your company.

Another cost saving for companies who implement a VOIP system is, because multiple offices, no matter where they are in the world are seamlessly connected, they can share many of the features VOIP can offer, such as:

1. One single receptionist

2. Auto attendant facilities

3. Voice mail system
